On calculating the capacity of surface runoff treatment facilities
(to be discussed)

Summary

It was demonstrated that for the most part of the territory of our country in the process of designing treatment facilities for surface runoff from the territories allotted for settlement and first group industrial areas the daily amount of snowmelt runoff is determinative. To calculate the capacity of the accumulating tanks and treatment facilities using the data on the amount of water in snow cover by the beginning of spring snowmelt is suggested. When using the suggested additions to the method of designing surface runoff treatment facilities the capacity of accumulating tanks increases approximately twice; whereas the capacity of treatment facilities is reduced approximately eightfold. The information on the implementation of the suggested approach in designing and constructing treatment facilities receiving surface runoff from the territory of Tarkett factory manufacturing flooring (Otradnyi, Samara Area) is presented.

Summary

The basic principles of the method for optimizing the calculation of volume-flow parameters of surface runoff (rain and melt) treatment facilities for the I–III category enterprises according to their negative impact on the environment are presented. The use of the method provides for reducing the design capacity of the treatment facilities by 3–5 times with a corresponding reduction in capital and operating costs while fully complying with the requirements of the current design rules as evidenced by the expert examination of design documentations.

Method for optimizing volume-flow parameters of airport surface runoff treatment facilities

Summary

Presented in the paper are the main provisions of developing a method for the optimization calculation of volume-flow parameters of surface runoff treatment facilities of the Russian airports, that belong to the category II of industrial facilities in terms of their negative impact on the environment. It is shown that using the proposed method with account of the period of de-icing of the aircrafts and airport territory provides for further reducing the design capacity of the treatment facilities by 1.7–2.45 times and the accumulation tank capacity by 1.2–2.1 times. At the same time, capital and operating costs are reduced with full compliance with the basic requirements of the current design rules and sanitary – environmental legislation.
